| 摘 要： | 目的]探讨矮败小麦高效育种技术平台。方法]对矮败小麦的创制和应用研究进展进行了总结,并提出了将单倍体育种技术引入矮败小麦高效育种技术体系的构想。结果]矮败小麦既保留了太谷核不育小麦雄性败育彻底、不育性稳定、开放授粉异交结实率高的特性,又发挥了矮变1号降秆作用强的特点,是较理想的群体改良工具。目前对矮败小麦的应用主要包括利用矮败小麦进行群体改良的种质资源平台、利用矮败小麦建立高效育种技术新体系的技术平台及利用矮败小麦作为新品种选育的生产平台。通过在已建立的小麦高效育种技术体系中引入单倍体技术的应用,从理论上建立了一套矮败小麦高效育种生物技术新体系。结论]该研究为矮败小麦的进一步研究及应用提供了参考。

| Abstract: | Purpose] The paper is to discuss the high-efficient breeding technology platform of dwarf male-sterile wheat.Method] Conclusion was made upon the development of the creation and application of dwarf male-sterile wheat,and the conception of introducing haploid breeding technology into the technological system of high-efficient breeding of dwarf male-sterile wheat was proposed.Result] Dwarf male-sterile wheat not only retains the properties of total male abortion of Taigu Genetic Sterile Wheat,steady sterility,and high hybrid rate after open pollination,but also has the characteristic of high dwarfing ability of Aibian No.1,becoming a comparatively ideal population modification means.At present,the application of dwarf male-sterile wheat mainly includes germplasm resources platform of population modification by using dwarf male-sterile wheat,technology platform of constructing new high-efficient breeding system by using dwarf male-sterile wheat,and production platform of using dwarf male-sterile wheat to breed new varieties.Through the introduction of haploid breeding into the already established wheat high-efficient breeding system,a new system of high-efficient biological breeding technology of dwarf male-sterile wheat was constructed theoretically.Conclusion] The study provides references to the further study and application of dwarf male-sterile wheat. |
